DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the rationalization of bagging work for telephone directories and the like in a logistics business aiming at improving work efficiency.

[0002]

2. Description of the Related Art For the time being, the conventional technology for bagging work associated with the delivery of telephone directories for which there is a high need for rationalization is described below. ”And the phonebook“ Hello Page ”) and distribute them to subscribers free of charge.
There is a gap of about six months in the time of renewal depending on each district version, but even so, the number of subscribers to distribute is enormous, and as a subscriber service there should be no early and late unfairness. In the meantime, delivery must be completed in a short period of time, about three weeks before the renewal month. For this reason, NTT distributes this delivery business for each region and outsources a series of delivery-related operations to a plurality of specialized logistics companies.

[0003] In a logistics company entrusted with this delivery business, as a preparatory work prior to delivery, a new occupational-specific bag is placed in a polyethylene bag printed with an NTT message for delivery of a new telephone directory provided by NTT. The two phonebooks “Town Page” and the phonetic alphabet “Hello Page” are combined and packed. However, the bagging work was burdensome, inefficient, and was becoming less profitable for the following reasons. That is, (a) Recently, the number of subscribers has increased and the telephone directory has become thicker and heavier. (B) It is troublesome to take out one bag each time from a given bundle of supplied polyethylene bags and widen the entrance of the bags, and pack two thicker and heavier telephone directories into this. The work is also troublesome. (C) For this reason, one worker manually completes one set of bagging work, although it depends on the skill level.
It takes 0 to 40 seconds, and the load is heavy. (D) Calcium carbonate is added to the supplied polyethylene bag so that there is no risk of environmental destruction even if it is incinerated. Since it is weaker and is easily broken by impacts, bagging must be done carefully to prevent damage. (E) However, the amount of commissioned delivery amounts to hundreds of thousands of sets a season, so this bagging operation has to rely on brute force sea tactics. (F) If this outsourcing business is not out of twice a year but out of the ordinary as a recurring business every month, perhaps the outsourced logistics company will also make some capital investment. Will build an efficient assembly line system. However, it is difficult to make a capital investment for the automation line with profits if it is commissioned only twice a year, and it has had to rely on temporary human tactics due to the recruitment of temporary workers. (G) However, these days, even for temporary jobs, hourly wages have increased, and it has become difficult for human resources to gather for such 3K labor, making it difficult for the commissioned work itself to be carried out. Now the profitability is getting worse.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned blocked situation of the commissioned business, and thereby, the logistics company commissioned by overcoming the various blocked situations described above. In contrast, the present invention provides a simple labor-saving device that functions such that the commissioned business becomes a worthwhile business as a profitable and profitable business. Next, the reason why the device of the present invention improves this commissioned business to a worthwhile business as a profitable and profitable business as a simple labor-saving device for bagging work of a telephone directory will be described below. Will be described.

[0005] One of the propositions aimed at by the present invention is to determine how much the level of automation and labor saving can be advanced. Abundant use of appropriate robots does not mean that full automation is not possible, but it is expensive in terms of cost, and is an over-investment and twice-a-year capital investment for outsourcing, which is difficult to amortize. Therefore, existing general-purpose cargo handling machines, such as "belt conveyors" and "roller conveyors", are diverted from the conventional ones, eliminating the need for manual bagging, which has become an efficient bottleneck in a series of operations. Developing a simple and effective automation and labor saving device, and connecting it to a conveyor, we have invented the idea of making online work online.

Another object of the present invention is to provide a dedicated labor-saving device for pursuing what has been a bottleneck of efficiency in the conventional work and eliminating the bottleneck. It is to develop. This requires the following two labor saving functions. (B) A labor-saving function that opens and sets the bag. It was thought that this could be achieved by combining several vacuum robots. However, assuming that it can be performed by simple manual operation, in the present invention, a slide guide as described in claim 2 is created, and the tip of the slide guide is denoted by reference numeral 9. A beak-shaped opening guide having a rounded shape as shown is provided, and the opening of the bag is applied to this tip portion, and as shown in FIG. The structure is such that sufficient bag opening and appropriate setting can be made simultaneously to accept. (B) A labor-saving function that slides down the phone book and packs the bag. This is to apply the own weight of the telephone directory and the inclination of the roller box indicated by reference numeral 5, and apply the appropriate speed and momentum to the stacked two telephone directories on the roller indicated by reference numeral 6 in an inclined state. Is a labor-saving device that slides down at an appropriate speed and momentum and automatically stores it in a set bag as shown in FIGS. The telephone directory, which is sent horizontally over the belt conveyor, automatically enters the roller box by the self-propelled power of the conveyor. In the case of a roller conveyor, it may be manually pushed lightly into the roller box. At this time, according to the present invention, reference numeral 19 in FIGS.
An automatic width adjustment function as shown by reference numeral 20 is provided in the roller box, and the superimposed telephone directory is automatically pushed to one of the box walls by applying an air cylinder or the like synchronized with the automation cycle. By aligning them, we have taken care to automatically align them in the horizontal direction so that the phone books stacked one above the other are aligned and guided to the slide guide without fail. In addition, when the "automatic width-shifting function" is not provided in the roller box for the above-described lateral alignment, the upright rollers are connected to both sides of the conveyor as shown by reference numeral 21 in FIG. A horizontal "roller guide" is provided. In this case, it is not necessary to adjust the width of the roller box denoted by reference numeral 5 to the width of the conveyor, but may be adjusted to the width of the slide guide. Therefore, it is possible to omit the automatic width adjustment function and to simplify the structure of the roller box. it can. If a conveyor dedicated to this operation is to be custom-ordered without using an existing conveyor, a conveyor whose width corresponds to the width of the telephone directory in terms of size may be applied. However, in this case, in order to arrange the telephone directory on the conveyor sequentially,
Care must be taken in the work to prevent lateral displacement. In addition, particular attention was paid to the invention of the device of the present invention, considering that the telephone directory is thick and heavy, and that the bag used is weak in strength and easy to tear, so that the speed and momentum of the descent are reduced. The test is repeated with respect to the impact and the like of the roller box, and the angle of inclination of the roller box and the slide guide connected thereto is carefully examined and selected.
Has been introduced. In particular, the delicate curve of the curved portion provided at the tip end allows the natural stoppage while mitigating the impact of downhilling, so that bags of weak materials are protected from damage and the load burden on workers who handle is reduced. Also brought.

The operation and operation of the apparatus of the present invention will be described below. (A) As for the operation of the device, as shown in the "conceptual diagram of the device operation" in FIG. 1, an existing general-purpose belt conveyor and the device of the present invention are combined and arranged and configured as a line of a line work. In order to apply the automated power, the "operation adjustment control device" must be used so that the work flow can be synchronized and operated in an orderly manner.
Is added. (B) The steps of the work are as follows: 1) The two types of received telephone directories are brought into the workplace and sorted, and one of each is taken out, and a set of superimposed pieces is prepared in advance as shown by reference numeral 1 in FIG. Keep it. This operation is almost the same as the conventional manual bagging. 2) Next, as shown by reference numeral 2, the above sets are sequentially
Work to put it on the conveyor. 3) Next, as shown by reference numeral 3, the present apparatus is operated to perform a bag filling operation. By connecting this device to a belt conveyor or roller conveyor, etc., the overall work efficiency can be reduced by mechanizing and labor-saving the "bagging work" in the conventional manual labor tactics. Enhance. 4) Finally, as indicated by reference numeral 4, the set of the telephone directory whose bagging has been completed is loaded into a container or the like. Hereafter, it is mounted on a vehicle and delivered as before. .

[0008]

The advantages and advantages of the present invention over conventional human naval tactical operations are described below. (A) The effects of the present invention to improve the work are as follows: 1) The labor saving and speeding up of the "bagging work" which has the largest work load among the conventional works. 2) The load on the worker is clearly reduced due to the progress of labor saving, and the conventional 3K-like work image is dispelled. 3) For this reason, it is easy to recruit temporary workers. 4) Since the flow work line is standardized, the work contents assigned to each worker are clarified, and surplus personnel can be reduced. Of course, you will not have to rely on traditional human tactics. 5) The work efficiency is increased, the productivity per worker is improved, and the total work cost can be significantly reduced. 6) In the trial production test, the manual bagging work varies depending on the skill level, from 20 seconds to 40 seconds per set. On the other hand, the present apparatus does not require much skill level. Even if a special temporary worker is in charge, the speed has generally increased from 4 seconds to about 6 seconds. B) The advantages of the device of the present invention are as follows: 1) The existing general-purpose cargo handling machine such as a "belt conveyor" or a "roller conveyor" can be temporarily diverted as a main axis of the assembly work. 2) At the same time, this device can be used flexibly as a general purpose dedicated machine for labor saving of bagging work. 3) It is possible to introduce an “automated and labor-saving device” that can eliminate the burden of loading the “bagging work”, which has been the biggest bottleneck so far, with a much lower investment than full automation. 4) By controlling the speed of automation, it is possible to select a work speed according to the worker. This allows
It is also possible to make accurate plans and forecasts such as work schedules.

[Estimation of economic effect] A logistics company has 40
Suppose you had commissioned a delivery business that involved packing 10,000 bags. In the logistics company, two workshops, 20
Carry out the work of bagging every 10,000 sets. Each workshop is
Temporary part-time job as bagging worker, hourly wage 850
The company hired a total of 40 people, 20 each in a circle, and planned to complete the work in 20 days. In addition, the speed of the work per worker is the average of the speed per set including the work time of the bag filling work and the work time of the process before and after the work.
Minutes, 60 sets of speed per hour. That is, when each worker works for 8 hours and 20 minutes a day and packs 500 bags per person, this work is completed in 20 days as planned. Therefore, when calculating the total labor cost of the part-time job required, 850 yen × 8 hours 20 minutes × 40 people × 20 days = 5,66
6,667 yen Next, it is assumed that two lines of the mechanized labor-saving apparatus of the present invention are introduced into each work place. The speed of bagging by this system is set to 4 to 6 seconds per set, so if the average speed is 5 seconds, 12 sets of bags can be packed per minute, and each line can be used for one day. After 7 hours of operation, 200,000 sets of bags are completed in 20 days. As described above, if the speed of the bagging operation is increased, operations such as unpacking, sorting, stacking sets, and opening the ears of the bag in the preceding and following steps must be accelerated. Even if the work that has to be accelerated is divided several times and all members take one hour in total, the work time per day can be settled in eight hours. Therefore, when the number of workers required for operation at each work site and every two lines incorporating the automation and labor saving apparatus of the present invention is determined from the test results, the number of workers required in the conventional art is 6 per line.
Efficiency has been improved so that two people can do the work of bagging by hand, which was done by humans.
A total of 16 people can be reduced, and the daily working time, which conventionally took 8 hours and 20 minutes, can be reduced to 8 hours. When the total labor cost during the work period is calculated, 850 yen × 8 hours × 20 days × 24 people = 3,264,0
00 yen Reduction of personnel expenses is 5,666,667 yen-3,264,000 yen = 2,4
02,667 yen In other words, it is possible to save 6 yen in unit price for one set of bagging work with only labor costs. Also, assuming that the development cost of this device is 4 million yen and the unit price of one device is 800,000 yen, the capital investment of 3.2 million yen for 4 devices is as follows:
In three seasons (one and a half years) you can amortize your investment costs,
Thereafter, it is possible to continuously save labor costs of 2.4 million yen every season.
